The paper presents an experiment on wireless communication in the terahertz band using a resonant tunneling diode receiver (Rx) and uni-travelling carrier photodiode transmitter. The use of intermediate-frequency-based transmission enables a low-complexity envelope-detection type Rx architecture for complex-modulated signals. Data rates of 60 and 68 Gbit/s are achieved for quadrature phase shift keying modulation and 16-level quadrature amplitude modulation respectively, with forward error correction enabling data recovery.
The authors report on a terahertz band wireless communication experiment employing a resonant tunneling diode receiver (Rx) and uni-travelling carrier photodiode transmitter. An intermediate-frequency based transmission facilitates a low-complexity envelope-detection type Rx architecture for complex-modulated signals. Forward error correction recoverable data-rates using quadrature phase shift keying modulation and 16-level quadrature amplitude modulation are 60 and 68 Gbit/s, respectively.
